Lesson Title: Population Distribution

State Standards: GLEs/GSEs

7c citing evidence of how natural selection and its evolutionary consequences provide a scientific explanation for the diversity and unity of past and present life forms on Earth. ">(e.g. Galapagos Islands, Hawaiian Islands, Australia, geographic isolation, adaptive radiation).
-selection can occur for more than one similar population contributing to earth's diversity (stabilizing, directional, disruptive)

8a illustrating that when an environment changes, the survival advantage /disadvantage of some characteristics may change
- environment changes may lead to the selection of extreme versions of the species (directional, disruptive, stabilizing selection)

National Standards:

Standard C: Life Science- develop an understanding of biological evolution (subtopic three).
  • the ensuing selection by the environment of those offspring better able to survive and leave offspring.
Standard F: Science in Personal and Social Perspectives- develop an understanding of population growth (subtopic 2)

Context of Lesson:

This lesson will introduce the three types of population distributions based on selection, which are: stabilizing, disruptive, and directional.
Overview of lesson, including: where it fits in unit, what are key ideas and what will students be doing.

Engagement:

Jelly Bean Lab:

1) Give students assorted colors of jelly beans (equal amounts of three colors- tell them they can collect more colors as populations increase)
2) Assign different scenarios for each group:
  • Red jelly beans=extreme (large)
  • Pink jelly beans=intermediate
  • White jelly beans=extreme (small)
